This invention relates to new and useful improvements in combined snow plows and sweepers and has for its primary object to provide a machine which may be employed for removing snow from roadways or as a sweeper.

A further object of the invention is the provision of a machine, for gathering snow from a roadway, provided with conveying mechanism adapted to convey the snow to the side of the roadway.

Another object of the invention is the provision of a machine of the above character which is designed to efliciently gather the snow and convey the same to a position for loading onto a vehicle.

Still another object of the invention is the provision of a combined snow plow and sweeping machine which is designed for connection with a tractor or which can be driven by a motor carried by the machine.

. A still further object of the invention is the provision of a machine of the above character which is comparatively simple and durable of construction and which will be efficient in operation.

Other ob'ects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawings forming a part of the specification and in which like references are employed to designate corresponding parts throughout the same:

Figure 1 is a top plan view of a combined snow plow and sweeper constructed in accordance with the present invention,

Figure 2 is a front-to-rear sectional view on the line 2-2 of Figure 1 looking in the direction indicated by the arrows,

Figure 3 is a side elevation of the machine,

Figure 4; is a transverse sectional view taken on the line 4' 1 of Figure 1, and

Figure 5 is a transverse sectional view taken on the line 5-5 of Figure 1.

Referring to the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, my 1mproved machine embodies a transversely extending hollow body 10 preferably formed of sheet-metal including a longitudinal rear wall 11 of rectangular formation and side walls 12 having their upper edges inclined downwardly toward the forward ends and projecting forwardly of the body to form the side plates 13 of a scoop structure. A curved bottom plate 14 is secured to the side plates 13 to form the bottom of the scoop the forward portion of which extends at a downward inclination with its forward edge located adjacent to the ground.

Rigidlv secured to the rear wall 11 and projecting rearwardly thereof is a rectangular frame 15 supporting an extension frame 16 detachably secured to the rigid frame 15.

Mounted in bearing brackets 17 upon the rear wall 11 is a horizontal rock shaft 18-. A lever 19 is fixed to one end of the shaft 18 and carries a pawl mechanism 20 for adjustable engagement with a toothed quadrant 21 rigidly secured to the rearwall 11. A lever link is pivotally connected with the forward end of the extension frame 16 and with arms 23 fastened to the shaft 18 so that a swinging movement of the lever 19 will efiect adjustment of the forward end of the scoop with respect to the ground.

Rigidly secured to the front of the body 10 adjacent the bottom thereof are a pair of frames 24 supporting swiveled wheel brackets 25 in which are journaled ground wheels 26.

Pivotally mounted, at its inner end, upon a shaft 28, at one side of the body 10, and proj ected laterally therefrom is a channel shaped conveyer section 27 the outer end of which carries a hood 29 pivotally connected therewith by means of a shaft 30. An actuating lever 31 is secured to each side of the hood 29 for conveniently swinging the same.

Rotatably mounted in the body 10 adjacent one end thereof and opposite the shaft 28 is a drive shaft 32'to the ends of which are secured a pair of sprocket gears 33. Similar sprocket gears 34 are secured adjacent the ends of the shaft 30, a pair of sprocket chains 35 being trained over the-sprocket gears 33 and 3 1. The end portions of the shaft 28 carry comparatively small idle sprocket gears 36 adapted to retain the upper stretch of the conveyer in horizontal movement. A pair of brackets 37 are secured to the inner sides of the casing body and contact with the upper sides of the upper stretches of the chains 35 maintaining the said upper stretches of the chains in horizontal position. Secured to the chains 35 and extending therebetween is a conveyer belt 38 carrying outstanding right angularly transverse blades 39 by means of which the snow is conveyed directly through the casing.

Rigidly secured to the side walls 13 of the body 10 are a pair of parallel horizontally extending brace bars 4.0, the forward ends thereof abutting a pair of parallel vertically extending bars 41. The upper ends of the bars 11 terminate above the scoop structure and are formed with bearings rotatably supporting a transverse shaft 42. The bearings are braced by a pair of forwardly projecting bars 43 to provide a durable journal structure. Rigidly secured to the shaft 42 and extending radially therefrom are a plurality of arms 44;.

Riveted or otherwise secured to the ends of the arms 44 and arranged in spiral formation are a plurality of blades 45. The said blades are arranged in two helical series so arranged as to elevate the snow onto the scoop and into the body. As clearly shown in Figure 1 the .ends of the shaft 1-2 project through the bearings and carry comparatively large bevel gears 46 rigidly secured to the shaft.

Rotatably mounted on the forward ends of bracket frames 47 is a cylindrically shaped brush 48. The inner ends of the frames 47 are rigidly secured to the bars 11 while the outer forward ends project forwardly beyond the scoop so that the brush will normally contact with the ground in front of the scoop. Rigidly fixed on one end of the brush shaft and adapted for rotatably operating the brush is a bevel gear 49.

As it is desirable, at times, to adjust the position of the pivoted conveyer section 27, means is provided for raising the section to provide for delivery of the snow at any desired elevation. This means includes a shaft 50 upon the adjustable section, rotatably mounted in the sides thereof. The outer ends of the shaft 50 carry a pair of winding drums 51 while a ratchet wheel 52 is secured on one end thereof. A crank 53 is attached to the Said end of the shaft 50 for rotating the same. A pair of ropes or cables 54 are secured to brackets 55 mounted on the outer end of the section and are trained over pulleys 56 rotatably mounted on the ends of a shaft 57, mounted in horizontal position adjacent one end of the body 10, and secured to the winding drums 51. By rotating the shaft 50 in a clockwise direction the pivoted casing section can be swung to an upward position as indicated by dotted lines in figure 4. The casing may be held in a desired position by engagement of the pawl 58, pivotally mounted on the side of the section, with the ratchet wheel 52. To lower the section 27, the pawl is elevated and the shaft permitted to rotate in a counterclockwise direction to unwind the cables.

As it is intended to impart motion to the brush 48, the scraper wheel, and the conveyer mechanism simultaneously during the movement of the machine over the roadway the machine is provided with a main drive shaft 59 extending; longitudinally at the rear of the body and having a non-circular extension 60 for connection with a clutch or transmission mechanism upon the tractor with which the machine is connected. The forward end of the drive shaft 59 is journaled in a bearing frame 61 and carries a bevel gear 62 which is rigidly fixed on the shaft. The gear 62 meshes with a similar bevel gear 63 fixed upon a shaft 64: extending through the bearing frame 61 and mounted in bearings 65 formed on bracket arms 66. One end of the shaft 64- extends beyond one end of the ofiset frame 16 and carries a bevel gear 67 which is fixed thereon. The gear 67 is in mesh with a complementary bevel gear 68 fixed on the rear end of the transverse conveyer shaft 32 to impart travel to the conveyer. The forward end of the shaft 32 also carries a bevel gear 69 which meshes with a complementary gear fixed upon a shaft 7 O rotatably supported in brackets 71 secured to the forward portion of the body 10, a pair of bevel gears 72 being secured to the ends of the shaft 70. The gears '52 mesh with bevel gears 73 fixed to the rear ends of forward angularly extending shafts 7d rotatably mounted in brackets 75 secured to the sides 12 of the body 10. The bevel gears 7 6 are fixed to the forward ends of the shafts 7d and are in mesh with the gears d6 carried by the shaft 42. A bevel gear 77 is also secured to the outer end of the shaft 70, this gear meshing; with a gear 7 8 fixed to the rear end of a shaft 79 rotatably mounted on one of the sides 13 of the body 10. The forward ends of the shaft 7 9 carries a bevel gear adapted to mesh with the bevel gear 49 secured to the outer end of the shaft.

In use, the machine may be readily driven by a tractor or may be equipped with a power unit for independent movement, and when connected to a tractor, the frame extension 16 is pivotally attached to the forward end of the tractor and the main drive shaft 59 is connected with a suitable power shaft or other prime mover.

As the machine is driven over a roadway, the gathering and conveying apparatus is driven by the gearing described at a suitable speed. W hen used for removing snow from the roadways, the rotary plow, comprising the blades 45, is suitably rotated to elevate the snow onto the scoop and cause the same to be deposited upon the endless conveyer 38. The

conveyer section 27 may be adjusted so as to discharge the snow in banks at the side of the roadway or may be elevated to deliver the snow into a conveying vehicle. When the frame extension 16 is rigidly secured to a tractor or similar draft means swinging move ment of the lever 19 will rock the structure about the carrier wheel 26 to adjust the position of the scoop with relation to the surface of the roadway, IVhile the machine is particularly designed for removing snow from roadways it may be also advantageously employed for removing other refuse such as leaves and the like. When used as a sweeper for leaves on roads and for street cleaning purposes the rotary plow may be removed if desired.

From the foregoing description and the drawings, it will be apparent that a compact and efficient snow plow and sweeping machine has been devised, constructed so as to gather snow or the like from the road or street surface and equipped with a conveying mechanism for delivering the snow' onto an adjustable conveyer section. The structure is designed to permit a discharge of the snow at one side of the roadway or to an elevated position from whence it may be deposited into avehicle.

The rotary action of the rotary plow structure is designed to loosen any solidified formation of the snow onthe road surface and to carry the same upwardly in the scoop to be deposited onto the endless conveyer.

Having thus described my invention, I claim,

1. In a machine of the class described, a hollow body, a conveyer supported for travel in said body, a scoop extending forwardly from the body and having its bottom curved upwardly and rearwardly from its forward edge, a shaft rotatably journaled above the scoop, arms radiating from the shaft, plow blades extending helically between the outer ends of relatively adjacent ones of said arms and supported thereby, the said blades being concentric to the said shaft, the blades constituting means for delivering snow upwardly and rearwardly over the bottom of the scoop and onto said conveyer, and a rotary cylindrical brush operatively mounted in advance of the said blades upon said shaft and constituting means for brushing snow from the surface of a roadway and delivering the same to position to be acted upon by said blades.
